<p>The coupling to join two flange sections together, and especially a clip for the ends of pipes, has a bolt (8) and nut (9) with movement through openings (6,7) in the clip straps (4,5). The nut has a radial flat (11) which extends into the opening, which is elongated with parallel longitudinal surfaces (12). The gap between the openings in the straps equals the tool key width between the flats of the nut. The nut has a stepped head (10) to apply axial pressure on the strap when tightened.</p> |
